Abstract: Abstract: A simulation study using finite element analysis (FEA) for the prediction of thermomechanical behavior of copper-shelled 3D printed electrodes during die-sink electrical discharge machining was presented. During the simulations, a 2D approach was followed due to the axis-symmetric shape of the electrode. The copper shell thickness was constant. The FEA analysis showed the mechanical behavior of copper-shelled SLA electrodes. A consideration of the influence of the various parameters on the electrode behavior can lead to the development of SLA electrodes, which can be loaded with higher currents, showing acceptable wear.
